i Application fled .Func 27,

To all whom it may concern) lle it known that l, Env-:1N QDELL, a citi- Vzen oill the United States, and a resident of Central City, iiithe county of Merrick and ytate of Nebraska, have invented vcertain improvements in Forceps,

My invention is an improvement in forceps and has for its object to` provide an instrument of the character specified, especially adapted for the use oit veterinary surgeons, as obstctrical 'torcepaavherein a series of blades is provided, mounted to move toward and from each other, but Without touching at their edges, and ilexible means in connection 'with the blades, and mounted in a plane transverse tothe axis about which the blades are grouped, ltor gripping the object to be removed, the flexible means being controlled to grip incoperation with the closing movement or" the blades.

in the drawings:

yfigure l is aplan viewY olf' the improved forceps, v Y

Eig. 2 is a partial"longitudinal section showing the operating mechanism,

n lg. 3 1s a partial side View with parts section, and the blades open,

Fig. Ll is an end view looking at the open edge blades,

Fir/s. 5 and 6 are sections on the lines 5-5ma c-e, of Fig. a.

ln the present embodiment of the invention, a handle or shank portion 1 is' provided, the said handle being hollow, leaving at one end a grip 2, and at the othera series .of blades 3 is pivoted or hinged to one end of the handle as indicated at 3. These blades are shown as slightly curved longitudinally, and are arranged With their convex faces outward.V rl`hey are sc shaped and mounted that they cannot touch at their adjacent edges, and hence cannot grip the mucous membrane of the mother, when they are closed.

These blades Yare pivoted 'between ears l on the shank and each has an eye 5 at its outer end. The blades are Vmoved. toward and 'from each other, by means of al lever which is pivoted to the shank at the grip, as indicated at 7, and the shank has a longitudinally extending slot at the lever.

A rod 8 is Vmounted to slide in the shank, being guided by bushings 9 held in the bore of the shank, and the rod extends out or' the shank at the end adjacent to the blades.

10 is mounted on the rod at the end, collar has radial lugs, to which are the inner ends of stretchers 1l, the blades.

@il collar and theV pivoted4 Whose outer ends are pivoted to The rod at the end adjacent to the leverv f 1s pivoted to one ci the Vmembers 12 or a toggle assembly, the other member 13 oit the assembly being pivoted to a'lixed member 14, held in a bushing 15 in the shank. A link 16 connects the lever 6 with the adjacent ends oi the levers 12 and 13, the said link having a head to which the levers are pivoted.

t will be evident that When'the lever is swung, the link 16 Will be moved transversely of the" shank, and Will swing' the toggle to cause the rod 8 to move longitudinally. When the rod is so moved the bla-des will beV moved toward' and from each other, through the stretcher connection.

The blades are relatively narroiv'and are hinged at` points sufficiently that they cannot abut at their adjacentedges vwhen they are closed.y rthe eye 5 and curve i of the yblade assist in holding the adjacent bladeedges spaced. .lt will be noticed that V.the toggle assembly is arranged in an eXtension 17 from the shank.

Flexible members 18, chains inthe present instance, are connected to cach blade, and each of these chains is slidable through the eye of the adjacent blade. Thus the flexible members are supported by the blades in a plane substantially at right angles to the axis about which the blades are grouped, in a loop, which may be opened andclosed.

That end of each chain remote 'trom the eye connection is secured to one end of a semi-rigid member 19, a Wire for instance, vand theseV Wires pass throughthe hollow shank to a connection with a controlling rod 20, mounted t0 slide in a bushing 20a, in the hollow shank, at the end remote from the blades 1 rlhe rod hagan eye 21 at its outer end, and a head 22 at its inner end, to Which the kWires are connected, and the lbushings 9 and 15 have longitudinally extending openings through Whichthe Wires pass. The shank has a flaring extension at the end adjacent to the blades, through Whose large end the Wires enter and pass through slots 24 in the shank kto the bore thereof, the slots being Within the extension.

ln operation, the forceps are introduced into the womb, in closed condition. As soon as the end with the blades touches a pig, for

far apart, so

vover theV animal, but also acting lum,

on the shank at the blades if desired.

lithlso'me slight manipulatiom'the mal or a portion thereof may be brought throughthe open loopor noose, formedby Vthe flexible member, it being understood that the opening of theblades opens andy spreads this noose. As soon as the animal yis Withinor partly Within vthe noose', the rod 20 is pulled to tighten the noose or loop on Vthe animal.

This movenjient not only tautens the flexiblemenibers, lbut acts to draw the blades together,` and ythe pig its tightly grasped vby* the flexible members and may be'easily removed. It is mpossibleto grip any portion of the mother, since the blades'nlever abut at their1 edges, and the tautening 'of the flexible 'membersy tends to clearthem from the sues of the mother.

lt lWill be y'evident .from the deSCIPQII that the flexible members constitute a noeste.

which may be engaged about the object and tightened thereon, the blades, the shank and associated parts constitutingv means for introducing the noose for o venin .and su porting it 1n a plane transverse to the axis onfthe obje`ct.v A
